Question about Office Equipment & Supplies
When switching on my projector, the lamp doesn't come on, only a faint internal noise is heard, no fan, and no LED indicating a problem.
You are most probably looking at a faulty Ballast Board wich is the lamp's power supply.
If the Projector makes a really hard humming noise it could be your Colourwheel that is faulty.
The unfortunate thing about a Colourwheel is that you can't fix it , you have to replace it. The fortunate thing is that it is a very cheap part to replace.
